To all whom it may concern:

Beit known that LRIOHARD V. WHITAKER, J r., a citizen of the United States, residing at .NewBrunswick, county of Middle'sex, and

State of New'Jersey, have invented certain new and useful Improvements in Grease Cartrid es or Containers, of which the following 1s a full, clear, and exact description.

' My invention relates to containers for lubricants, for example axle-grease, and is designed more articularly for automo bilists use. Its c ief object is to provide a cheap and effective container or cartridge which can be furnished filled or loaded with suitable lubricating material, so as to be ready for instant use at any time.

To this and other ends the invention comprises the-novel features of construction hereinafter described. r

The preferred embodiment of-the invention is'illustrated in the annexed drawing,

.be lubricated.

in-which Figure 1 shows the cartridge or container .in" longitudinal section. Fig. 2-is a part-sectional view'showin convenient and eifective devices for expe ling the grease from the.

cartridge and applying it to the parts to The body of the cartridge, desi 1, 'is preferably cylindrical in orm and .made of inexpensive material, for example .thebody, to which t e flange 1s sol thin sheet brass,.tin, etc. At-one end the body is provided with a bulging or convex cap.2.having a flan e 3 fitting snugly over ered or otherwise permanently secured. At' the center of the cap is a neck 4, formed with screw-'threads,f.as shown, to receive a removable screw-plug member or stopper'5. .On the opposite end is an annulus 6, also threaded, and of somewhat largerv diameter than the body. This end of the cartridge 15 closed bya threaded cap member 7 screwed,

. into the annulus.

Both the neck and the annulus are made of sheet metal, and "the threads-are formedpreferably by rolling or spinning. The edge of each is extended out wardly to form inclined lips 8, 9, and the closure members 5, 7 are formed with out wardly extending flanges 10, 11 so that ive for such pur ose. The flange 11 may be suitable materia ated by convenient grasping byv the hand. This part, and the edge of-flange 10, are prefer-- ably milled or knurled to afford a firm gripping surface for the fingers. The cartridge is filled with the desired material, for example grease of the usual viscous or semisolid consistency, and the closures are screwed in so as to bring their flanges into, I

firm contact with the resilient lips; after which the cartridge can be handled without danger of soilin the hands or clothing.

. Simple and e ective devices for expelling and applying the grease are shown in Fig; 2.

In this figure, 13 designates a ta ering discharge member or nozzle provi ed with a threaded base member 14. which canbe screwed into the neck 4:. The disk or head member 15 has a threaded flange 16, to fit inside the annulus 6, and also carries a tu-- bular stem 17. Threaded on the stem is a gland or stufling box 18', provided w1th wings 'or' pins 19 by which it may be readil turned for removal and replacement. Sh

in through the stuflingbox and stem is a re .20, having at its inner end a head 21 composed of rin 22, of leather or other gripped firmly between two disks 23, 24. On the other end of the rod is a handle 25. The inner diameter of the threaded flange of the cap'.l5 is. referably slightly larger than the inner 1am-' eter of the body of the cartridge so that when the plunger is drawn back to its full extent the disk 24 on the head 21 will be substantially flush with, the edge of the threaded flange 16 and the plunger-will lie wholly within the cap.

When the grease is to be used the closure members 5 and 7 are unscrewed, the discharge member or nozzle 13 is screwed into the neck 4:, and thehead memberorxdlsk 15,

with its plunger retracted, is screwed into the annulus 6. Pressure on the plunger will now expelthe contents of the cartridge throughthe nozzle, thus enablingl the grease to be applied, .;quickly and wit out waste, directly to the part orparts which are to be lubricated. When the operation is finished the expelling devices may be left on the body of the cartridge or they may be removed and the original closures replaced, as desired.

As before stated, the cartridge is fur- :nished loaded; it is also cheaply made, iofso that when emptied inexpensive material, it may be thrown awaywithout loss, the

user of course retaining the expelling and applying devices for use with another cartridge. It will thus be seen that my improved container or cartridge afiords a convenient and efiz'ective method of carrying and applying lubricant. The cartridge being furnlshed already loaded, the user issaved the inconvenience of filling the container. He simply attaches the nozzle and plunger, and applies the grease in such quantity as may be'needed.

n It is to be understood that the form herein specifically shown and described is merely provided with an interior screw thread and an outwardly projecting resilient flange at the extremity of said enlarged end, a cap secured on the opposite end of the body portion and formed with a threaded neck of less diameter than said body and interiorly threaded, said neck having a resilient outwardly projecting terminal lip, and members adapted to be screwed into said thread ed portions of the cartridge provided with flanges arranged to engage the resilient lips and form hermetic joints.

In testimony 'fwhereof- I aflix. my signature 1n the presence of two subscrlbing wltnesses.
